Abstract

This paper proposes a new configuration of the switched-capacitor multilevel inverter (SCMI). The proposed switched-capacitor nine-level inverter configuration uses the capacitors to raise the output voltage level and boost output voltage. Based on switching the capacitors in series and in parallel through the semiconducting switches, the capacitors can be balance without using auxiliary circuit. The proposed topology does not use more power supplies, moreover the proposed inverter of components are used less than the traditional inverter configuration, thereby reducing the cost and size of the system. To verify the circuit operation, PSIM simulation is performed for 9-level configuration. The experimental results are also shown with 9-level inverter configuration.
